Nuclear theory sits at the fascinating intersection of particle physics and the forces that hold our universe together. This field explores how protons and neutrons bind inside atomic nuclei, seeking to understand the fundamental interactions that govern matter at its most dense and energetic levels. While the mathematics involved can be incredibly complex, the core questions are deeply human: how does the universe function at its smallest scales, and what happens when we push matter to its limits?
At Gist.Science, we make these cutting-edge discoveries accessible by processing every new preprint published in this category on arXiv. Our team transforms dense academic manuscripts into clear, plain-language summaries alongside detailed technical overviews, ensuring that both experts and curious readers can grasp the latest breakthroughs without getting lost in the jargon. Below are the latest papers in nuclear theory, distilled and ready for you to explore.
Using the parity doublet model, this paper demonstrates that gravitational waves from the nuclear liquid-gas phase transition in QCD could produce detectable signals in the millihertz to nanohertz bands, whereas those from the chiral phase transition are too weak to be observed, thereby linking the chiral invariant mass to potential gravitational wave signatures of nucleon mass origins.
This paper presents a rigorous construction and uniqueness proof for the matrix Green's function of coupled radial Schrödinger equations with symmetric potentials, demonstrating its diagonal Wronskian structure and illustrating its application in capturing multistep excitation pathways within the continuum-discretized coupled-channels framework.
This paper investigates the photoproduction and nuclear absorption of charmonium on C and W targets near the kinematic threshold using a collision model with nuclear spectral functions, demonstrating that calculated observables are sensitive to absorption scenarios and could help determine the -nucleus cross section for future experiments at the CEBAF facility.
This paper establishes an analytical connection between triaxial nuclear shapes and three-particle correlations in relativistic heavy-ion collisions, demonstrating that specific flow and momentum fluctuation observables are directly proportional to the nuclear triaxiality parameter .
This paper utilizes Hartree-Fock-Bogoliubov and relativistic Hartree-Bogoliubov theories to demonstrate how continuum coupling restores neutron radii by canceling pairing anti-halo effects and to characterize soft dipole excitations in deformed halo nuclei like Ne-31 and Mg-37 as indicators of deformation and halo configuration.
This paper presents the first systematic off-shell covariant unitarized chiral effective field theory investigation of the meson-baryon interaction up to next-to-leading order, confirming the validity of on-shell approximations for scattering observables while eliminating unphysical left-hand cuts and providing the first predictions for femtoscopic correlation functions to further constrain the nature of the resonance.
This paper demonstrates that Bose polarons immersed in a Bose-Einstein condensate can exhibit topological properties, including emergent Weyl nodes, nonzero Berry curvature, and chiral anomaly, driven solely by interspecies -wave Feshbach coupling without the need for spin degrees of freedom or spin-orbit coupling.
By combining triaxial relativistic Hartree-Bogoliubov theory with the Glauber reaction model, this study identifies aluminum isotopes Al as the first candidates for triaxially deformed one-neutron -wave halos, evidenced by their anomalous reaction cross sections and narrow momentum distributions.
This paper presents a fixed-particle-number quantum simulation of cranked zirconium isotopes using a structured, number-conserving VQE ansatz that introduces a novel pairing-coherence diagnostic () to analyze rotational evolution and pairing correlations in a truncated active space.
This paper presents the first microscopic prediction of reaction observables for the two-neutron halo candidates F and Na by combining the deformed relativistic Hartree-Bogoliubov theory in continuum with a validated Glauber reaction model, confirming their dilute halo structures through agreement with experimental cross sections and characteristic momentum distributions.
